A2FO107 Rexroth Bent Axis Axial Piston Pump 106.7cm³ 400bar

Product Overview

The A2FO107/61R-PBB05 is a Bosch Rexroth A2FO series (series 61) bent-axis fixed-displacement axial piston hydraulic pump designed for open circuits. Featuring a precision tapered-piston rotary group and one-piece pistons with piston rings, it offers an excellent power-to-weight ratio and overall efficiency. Our A2FO107 and companion sizes A2FO45, A2FO56, A2FO63, A2FO80, A2FO90 are manufactured to original technical specifications, offering 100% interchangeability (flange, shaft end, and port positions fully match OEM) and 100% simulated-duty testing. They deliver reliable high-pressure performance as cost-effective direct replacements for genuine Rexroth pumps.

Key Technical Advantages

1. Precision bent-axis piston design with one-piece pistons and piston rings delivers superior volumetric and hydro-mechanical efficiency, high power density, and smooth operation.
2. Patented cylinder block drive system and quality materials support continuous high-pressure duty with excellent starting characteristics and low noise.
3. Compact construction and optimized bearings provide long service life and easy maintenance, suitable for diverse machine integration.
4. Full dimensional and performance interchangeability plus rigorous simulated-duty testing guarantee drop-in replacement of original Rexroth units, minimizing downtime and lifecycle costs.

Application Areas

Ideal for construction equipment, agricultural machinery, mining equipment, marine applications, industrial hydraulic power units, and mobile machinery requiring reliable fixed-displacement high-pressure oil supply in open circuits. Typical uses include excavators, loaders, cranes, concrete pump trucks, drilling rigs, rollers, and various hydraulic systems.

Expert Maintenance Tips

• Verify exact match of mounting flange, shaft end (keyed or splined), and port orientation before installation; ensure adequate suction pressure; avoid forced assembly.
• Maintain hydraulic fluid cleanliness to recommended standards (ISO 4406 or NAS 1638) using anti-wear mineral oil; regularly check case drain pressure and temperature.
• Monitor speed, pressure, and flow during commissioning; avoid prolonged over-pressure or cavitation.
• Use matching filter elements and seals during service; record operating parameters to detect early efficiency decline.
